lets do some math using the lowest roll
100% * 1,260 xp per kill + monster XP * 1.58%
lets say monster XP is 1000
100% *( (1,260 + 1000) * 1.58)= 2840 xp for 1 kill using 1 item
Ok now lets see here you have 2 rings and an amulet
Hell Fire ring set up the same way that's another 35%
and 1,260 xp per kill
Leorics signet is another 35% and 1,260 xp per kill
and I'm sure you can figure out the rest 3-4 pieces of gear can net you quite a bit in the way of experience.
